Michael's comment and note:
- Generally, data recording has been poorly done for most grade 6 students. Worm moved 6 cm away from light - is this a good observation?
- Students can better attempt to control the controlled variable. When light is being tested on the worms, is it better to dim the light in the room? Why?
- Some students have been noted to be unprepared for experiment. E.g. forgetting apparatus, not planning for the independent variable.
